PUMP.

To all whom t may concern Be it known that I, ISAAC R. SToU'r, a citizen of the United States, residing at Medicine Lodge, in the county of Barber and State of Kansas, have invented certain new and useful Improvements in Pumps, of which the following is a specification,

This invention relates to that class of pumps comprising pump barrels, together with means for alternately introducing compressed air into the barrels.

and, Fig. 19 is a detail sectional view through the friction disk and its shaft.

In the drawings wherein is illustrated a preferred embodiment of my invention, attention being called first to Fig. 1, the numeral 17 designates an explosive engine as a whole of any well lmown or preferred type. This engine rotates a pulley 18, engaged by a belt 19, which is trained about pulley 20 of an air compressor 21 of any well known or preferred type. This air compressor is shown as being vertically disposed and'compressed air is discharged from the opposite ends of the same through pipes 22 and 23 into a common pipe 24. The pulley 20 has a pinion 25 rigidly connected therewith, which drives a pinion 26 serving to operate the air compressor and also having a pulley 27 rigidly connected therewith. The pulley 27 is engaged by a bolt 28, engaging a step pulley 29, which issuitably supported by brackets or uprights 30. This step pulley is engaged by a belt 31, engaging a trip wheel 32, suitably mounted upon uprights 33 and having a portion of its periphery cut away for forming a semicylindrical recess 34, as shown. As more clearly lshown in Figs. 2, 3 and 15, a stationary support or bracket is provided, in-

cluding uprights 35, rigidly connected with a plate 36, which is clamped to pipes 37 and 38 through the medium of bolts 39, engaging an-oppositely arranged plate 40. Fulcrumed upon the upper end of this stationarysupport is an oscillatory operating lever, comprising a rod 41 rigidly connected at one end with spaced rods 42 and 43, which are pivoted with the uprights 35 through the medium of a transverse pin 44. The rod 41 has a weight 45 preferably adjustably mounted thereon and this weight may be clamped to the rod 41 by any suitable means. At the free en d of the rod 41 is a spring 46, connected therewith by bolts 47 or the like. This spring is adapted to slidably engage the periphery of the trip y wheel 32, wherebyafter said trip wheel has been rotated a half revolution the spring 46 will oscillate within the recess 34 to remain therein during the next half revolution of thewheel32. By the above described means the oscillatory operating lever is automatically actuated, for a purpose to be described.

-In Fig. 4, I have illustrated a slightly different form and arrangement of the air compressor. In this ligure, the numeral 48 designates the horizont-ally arranged cylinder of the air compressor, within which reciprocates the piston 49, connected with piston rod 50, having connection with pit man 51, which in turn-has suitable connection with the crank shaft of theengine 17. In this view the pulley 29 is driven directly from the pulley 18 through the medium of a belt 52. All other associated, members remain the same. The pipe 24 has conmunication with a vertical pressure storage tank 53, to the upper end of which are connected a pressure supply pipe 54 and an auxiliary pipe 155. The tank 53 is equipped with a pressure indicator 56 and a safety valve 57, connected therewith, as shown The numeral 58 designates a tank disposed below tank 53 and connected with pipe 24 through a pipe 59, which carries a cut-0H valve 60. The pipe 24 is equipped with a check valve 61, adapted to permit of the passage of the air from the air compressor to the tank 53 butto prevent the back flow of the air. The tank 58 is connected with a pipe 62, which is connect-ed with a common discharge pipe 63 and provided with a check valve 64, adapted to permit of the flow of water from the pipe 63 into the tank 58 but to prevent the reverse flow of they water. Between the valve 64 and the tank 58 is disposed the lower end of a pipe 65 having connection with the pipe 62, as shown, and provided near it-s upper end with a cutoff valve 66.

As more clearly shown in Fig. 5, the auX- iliary pipe has connection through the medium of a suitable coupling with a valve casing 67, which is connected with the lower end of thevert-ical pipe 37. This valve casing contains a vertically movable downwardly opening valve 68, mounted upon the lower screw-threaded end of valve rod 69, which extends vertically through and beyond the pipe 37, to operate within a stuifing box 70, serving to close the upper end of the pipe 37. The valve 68 is so shaped that when the same is lowered to disengage the lower end of the pipe 37 or its seat, the

compressed air may freely pass from the pipe 55 through the pipe 37. The vertically arranged pipes 37 and 38 are each formed in two sections, connected by couplings 71 and 72, respectively, said couplings vbeing provided upon adjacent sides with internally screw-threaded nipples 73, engaging an externally screw-threaded coupling v74 whereby communication is Ahad between the two vertical pipes 37 and 38. The coupling 72 serves as a valve casing for a vertically movable upwardly opening valve 74, adapted to engage the upper end of t-he lower section of the pipe 38 when in its closed position. The valve 74 is mounted upon a screw-threaded portion of a valve rod pipe at its upper an\d lower ends, to operate through stuing boxes 76 and 77, which serve to close the ends of the pipe 38. The

pipe 38 is provided below the valve 74 with an opening 78 formed therethrough, whereby communication may be established between the interior of the pipe 38 and the atmosphere. The coupling 72 is provided upon its outer side with a nipple 79, having connection 'with an elbow 80 through the medium of a coupling 81, which elbow is connected with a pipe 82, provided intermediate its ends, as shown in Fig. 5, with a coupling 83, having a nipple formed thereon, which is normally closed by a cap 84. The function of the coupling 83 is to provide means whereby oil or other lubricant may be fed into the pipe 82, for a purpose to be described.

As shown in Fig. 15, the spaced rods 42 and 43 have pivotal connection respectively, with depending links 85 and 86, which are in turn pivotally connected with the piston rods 69 and 75, respectively.

From the description of the above referred to parts, it is obvious that the oscillatory operating lever is employed to operate the valves 68 and 74, said valves being so constructed and arranged that when one of them is opened, the other is closed. The pipe 82 extends downwardly for connection with a vertical pipe 87, the upper end of which is connected with the lower end of a valve shifting cylinder 88, such connection being eected through the medium of a head 89.

As shown in Fig. 7, the numeral 90 designates an auxiliary cylinder, having itsupper and lower ends closed by heads 91 and 92, which are clamped to the cylinder by bolts 93. The lower end of t-he vertical pipe 87 extends through and has connection with the head 91. A piston rod 94 is mounted to reciprocate within the pipe 87 and has its upper and lower end portions disposed within cylinders 88 and 90. The lower end of the pipe 87 is closed by a metallic stutling box 95 through which the piston rod 94 operates. Within the valve shifting cylinder 88 is mounted a piston 96, rigidly connected with the rod 94, as shown. The cylinder 88 is provided at its upper end with an opening or air-vent 97 and this cylinder 88 also has connection and communication with a smaller cylinder 98, the lower end of which is formed open, as shown. Within the cylinder 98 is mounted to reciprocate avpiston 99, connected with a reciprocatory rod 100, disposed tostrike against or' engage the upper-end of the rod 94. The rod 100 has a coil spring 101 surthe pipe 54 is provided near the cylinder ciprocatory valve rod 109, extending axially rounding the same, the upper end of which v engages with a head 102, serving to partially close the upper end of the cylinder 98. The pressure supply pipe 54 is connected and has communication with the upper end of the cylinder 98, as shown, and

98 with a coupling 103, which connects the pipe 54 with a pipe 104.

As shown in Fig. 7, the pipe 104 has connection with a vertical pipe 105 through the medium of a coupling 106. The pipe 105 is vertically disposed and extends through the head 91 of the auxiliary cylinder 90, to have the lower perforated portion 107 thereof disposed within the cylinder 90, as shown. The lower end of the pipe 107 is closed by a head or cap 108, apertured to receive a rewithin the pipe 105 and carrying intermediate its ends a valve 110, which is mounted within the coupling or valve casing 106. T he valve 110 is a double action valve. The pipe 105 is connected at `its upper end with an elbow 111e, which is connected with a pipe 127. A pipe 111 connects pipe 127 with a vertically disposed pipe 112, extending through the head 91 of the cylinder 90, as shown, and provided` with external screwthreads to engage the upper end of a housing 113, having apertures 114 formed therethrough. The housing 113 has its lower end closed by means of a plug 115, having an opening formed therethrough to receive a reciprocatory valve rod 116, carrying near its upper and lower ends valves 117 and 118. The valve 117 is disposed'within a coupling or valve casing 117a and the same is unseated by an upward movement. The valve 118 is unseated by a downward movement and it is obvious that the valves 117 and 118 are moved at the same time by rod 116, whereby one of the valves is always unseated while the other is seated. The valve 110 is in effect a double valve and is seated when moved sufficiently upwardly or downwardly. The pipe 112 has connection with a common exhaust pipe 119, through the medium of a coupling 120. The valve rods 109 and 116 have their lower ends disposed within sleeves 121, carried by a transverse bar 122, which is connected with a bracket 123 by means of a bolt 124 or the like. The rods` 109 and 116 carry nuts 125, disposed above the sleeve 121, and between said nuts and sleeves are disposed rubber washers 125 or other shock absorbing means. The bracket 123 is apertured, as shown at 126 to receive the rod 94, which carries nuts 126, and between nuts 126 and the horizontal arms of the bracket 123 are disposed rubber washers 126e. The pipe 54 is provided near its upper end with a coupling 126b, similar to coupling 83 (see Fig. 5) whereby oil may be fed into pipe 54 to lubricate the pistons 99 and 96 and other parts. The pipes 54 and 55 are provided near their upper ends with cut-off valves 54 and 55', respectively, which are both open when the machine is in operation.

As clearly shown in Figs. 1 and 11 to 14, inclusive, I provide a pair of superposed pump barrels 128 and 129. A pipe 130 (see Fig.' 7) connects kthe auxiliary cylinder 90 and the upper end of the upper pump barrel 128, as clearly shown in Figs. 11 and 16.

Each of these pumpbarrels comprises a cy-` rels is provided with a perforated inlet pipe 137, engaging within a screw-threaded opening formed in the head 132. Surrounding the pipe 137 is a conical perforated strainer' 138, the upper larger end of which receives the head 132 and is secured thereto by a clamping ring 139. A second clamping ring 140 surrounds the lower smaller end of the strainer 138 and clamps the same to the perforated pipe 137. rIhe lower portion of the pipe 137 of the upper barrel 128 is closed by a plug 141 while the extreme lower end of the pipe 137 or that portion disposed below the plug is not perforated but is internally screw-threaded for engagement with a pipe section or coupling 142, which engages within a screw-threaded opening formed in the head 131 of the lower pump barrel, as shown. The pipe 137 of the lower pump barrel has its lower end closed by a cap 143, as clearly shown in Fig. 14. The pipe 127 (see Figs. 1, 11 and 7) has connection with or continues in a pipe 144, extending vertically and downwardly for connection with pipe 137, between the upper and lower pump barrels and leads into this pipe below the plug 141, as clearly shown in Fig. 11. A pipe 145 extends downwardly for connection with the lower portion of the upper pump barrel `128, is provided with a check valve 146 to permit of the water passing upwardly therein and the upper end of this pipe is connected with the common discharge pipe 63 by a coupling 147. rlhe common ydischarge pipe 63 is vertically disposed, is provided near its lower end with a check valve 148 to permit of the water passing upwardly through the same and has connection with the lower pump barrel 129 near the lower end of the same. The numeral 149 designates upper and lower clamping strips, surrounding pipes 63, 145, 144 and the upper pump barrel 128, for securing the same together and holding them in their proper requisite positions. The upper end of the lower pump barrel 129 is engaged by a clamping strip 150, surrounding said pump in substantially the same manner as de-i scribed in connection with the first form o-f the invent-ion. The pipe 144 leads directly through the head 131 of the barrel 129 and the pipe 130 has the saine connection with the barrel 128. All other parts of the apparatus remain substantially the same.

The speed changing means shown in Figs. 17 to 194 is adapted for use in connection with either form of air colnpressor, as shown in Figs. 1 and 4. As shown in Figs. 17 to 19, the trip wheel 32 is driven by a friction pulley 150 disposed at right angles to the trip wheel 32. The trip wheel 32 is rigidly mounted upon a longitudinally movable shaft 151, journaled through bearings 152 and engaged by a leaf-spring 153, which yieldingly holds the wheel 32 and the pulley 150 in proper frictional engagement. The friction pulley 150 is disposed upon a shaft 154, which is journaled through bearings 155. The shaft 154 has one end reduced, as shown at 155a and carries near its opposite end a ring 1551, fast thereon, whereby the shaft 155 cannot have any perceptible longitudinal movement. A sleeve 156 is splined upon the shaft .154 to move longitudinally thereof and is provided at one end with a flange 157, rigidly connected with the friction pulley 150 through the medium of bolts 158 or the like. A ring 159 has screw-threaded engagement with the opposite end of the sleeve 156, forming with kthe flange 157 an annular recess 160 to receive an annular head 161, which is loosely mounted upon the sleeve 156 and formed on one end of a shifting lever 162. The shifting lever 162 operates wit-hin a `fixed guide bracket'163 and may be locked in adjustment at different vpositions by a clamping bolt 164.

From the description of the above referred to parts, it is obvious that by proper manipulation of the shifting lever 162, the friction pulley 150 may be moved toward or away from the center of the trip wheel 32, thus changing the speed of rotation of the trip wheel, which is imparted thereto from the friction pulley. 150. The friction pulley 150 receives its rotation from a pulley 165, fast upon the shaft'154 and driven by the belt 28, shown in Fig. 1 or the belt 52 shown in Fig. 4. When this speed changing means is employed the step pulley 29 will be dispensedwith.

y In the operation of the apparatus, the engine is started and the air compressorset in motion to store compressed air in the tank 53. The engine operates in the direction to cause the tripping wheel 32 to rotate counter-clockwise, as indicated by the arrow. Assuming that this tripping wheel occupies the position as shown in Fig. 2, the operating lever including the rod 41 will be oscillated downwardly whereby the valve 68 is seated and the valve 74 unseated, as clearly shown in Fig. 5. The lower portion of t-he cylinder 88 has communication with the atmosphere, through pipes 82, 38 and the opening 78. The valve 68 being closed, the compressed air cannot pass through the pipe 37. The compressed air passes through the supply pipe 54 into the cylinder 98 above the piston 99, forcing thesame downwardly, whereby the piston 96 in `cylinder 88 is driven downwardly. When this takes place the valve 110 (see Fig. 7 is lowered and seated for closing the. upper endv of the pipe 107, the valve 117 is lowered and seated for closing the upper end of the pipe 112 and at the same time valve 118 is unseated. The upper pump barrel 128 is now in communication with the atmosphere, through the medium of pipe 130, cylinder 90, pipe 112 and pipe 119. The compressed air is now supplied to pipe 54, pipe 104, and pipe 127 rel 129. The upper pump barrel 128 is now being filled'with water, the valve 134 opening upwardly to allow the entrance of the water, it being understood that the two barrels are submerged in the water. The lower pump barrel 129 having been previously filled with water, such water is forced by the compressed air now being introduced into this barrel, out through the common discharge pipe 63. By the time the barrel 129 a half a revolution to oscillate the operating lever upwardly, whereby valve 68 is unseated and valve 74 seated (see Fig. 5). When this occurs compressed air is supplied to pipe 55 and pipe 82 into the cylinder 88 below the piston 96. The communication that the cylinder 88 previously had with the atmosphere, is now cut off by the valve 74 being seated. The pressure in the cylinder 88 is exerted against piston 96 and at the same time pressure supplied thro-ugh pipe l 54 is being exerted in cylinder 98 above pisi ton 99, but the cylinder 96 being of the greater area will prevail and be elevated,

l carrying with it piston 99. Valve 110 will then be'elevated to occupy the position shown in Fig. '7 for preventing the compressed air from passing upwardly through pipe 105 into the upper end of the lower pump barhas been emptied, trip wheel 32 has rotated` but permitting the same to pass downwardly into cylinder 90, from which it passes into the upper pump barrel 128 through pipe 130. The valve 118 is in its upper seated position while the valve 117 is elevated and unseated, whereby the interior of the lower pump barrel 129 will have communication ywithl the atmosphere, through the medium of pipe 144, pipe 127, pipe 112 and thecommon exhaust pipe 119. This lower pump barrel is now being refilled. The com-` pressed air passing through the pipe 130 in the upper end of the cylinder 128 forces the water out of Athe same, which now passes through pipe 145 and the common discharge pipe 68. Then the trip wheel 32 is rotated the next one-half revolution the o-perating lever is again oscillated downwardly and the above described operation repeated.

When the means shown in Figs. 17 to 19 is employed, it is obvious that the speed of rotation of the trip wheel 32 may be easily changed, as may be required. It is thus seen that the operation of my pump as a whole is automatic and continuous. By closing the valve 6G and the valve at the discharge end of pipe 63, the pump will discharge the water through pipe G2 into the tank 58 to store the same therein. This stored water is forced from the tank 58 through pipe 65 by introducing compressed air into the tank which mayl be accomplished by closing valves 54 and 55 and opening .valve 60.-
